Insulated the metal shed roof for summer

The shed has been marvellous so far, but as foretold by mates Gerald and Ralph, the weak spot will be heat from the sun beating on the corrugated metal roof.

Indeed, when the sun is on the roof, it's like a radiator inside. I purchased R3 poly bats, which I had to split in half so they're around R1.5. Backed and held in place with masonite board. It now looks like this inside:

It's a pretty rough job but the effect is a huge improvement in comfort when the sun is beating down. Foolishly I went along with the offered skylight and of course this isn't desirable in full sun so I've placed the 65W solar panel over it and it covers it pretty well.

I could go on and insulate the walls but wood is a pretty good insulator already so I think the most important job has been done.

A piece of advice, determine beforehand how much R-value you need. A shed used to store tools won't need much, if any, insulation, while a shed in which you spend time working will require considerably more.
